CSH visualization expert Johannes Sorger presents a project co-authored by himself and Wolfgang Knecht together with Alessio Arleo, Peter Kán, and Manuela Waldner (all TU Wien) at the Pacific Graphics 20+21 conference.

The conference takes place in Wellington/New Zealand from October 18 to 21, 2021 and is organized as a virtual event.




To exploit the potential of immersive network analytics for engaging and effective exploration, we promote the metaphor of “egocentrism,” where data depiction and interaction are adapted to the perspective of the user within a 3D network. Egocentrism has the potential to overcome some of the inherent downsides of virtual environments, e.g., visual clutter and cyber-sickness.


To investigate the effect of this metaphor on immersive network exploration, we designed and evaluated interfaces of varying degrees of egocentrism. In a user study, we evaluated the effect of these interfaces on visual search tasks, efficiency of network traversal, spatial orientation, as well as cyber-sickness.


Results show that a simple egocentric interface considerably improves visual search efficiency and navigation performance, yet does not decrease spatial orientation or increase cyber-sickness. Local layout optimizations of the neighborhood only marginally improves the user’s performance.


We tie our findings together in an open online tool for egocentric network exploration, providing actionable insights on the benefits of the egocentric network exploration metaphor.



About the conference:


The 28th and 29th Pacific Conference on Computer Graphics and Applications (Pacific Graphics 20+21) will be jointly hosted in Wellington, New Zealand from October 18 to 21, 2021. Pacific Graphics is an annual flagship conference of the Asia Graphics Association. As a highly successful conference series, Pacific Graphics provides a premium forum for researchers, developers, practitioners in the Pacific Rim and around the world to present and discuss new problems, solutions, and technologies in computer graphics and related areas.
